MIXING VALVE USAGE

This appliance has been design certiﬁ ed as complying with

American National Standard/CSA Standard for water heaters

and is considered suitable for:

Water (Potable) Heating and Space Heating: All models are

considered suitable for water (potable) heating and space heat-

ing.

HOTTER WATER CAN SCALD:

Water heaters are intended to produce hot water. Water heated

to a temperature which will satisfy space heating, clothes wash-

ing, dish washing, and other sanitizing needs can scald and

permanently injure you upon contact. Some people are more

likely to be permanently injured by hot water than others. These

include the elderly, children, the inﬁ rm, or physically/mentally

handicapped. If anyone using hot water in your home ﬁ ts into

one of these groups or if there is a local code or state law requir-

ing a certain temperature water at the hot water tap, then you

must take special precautions. In addition to using the lowest

possible temperature setting that satisﬁ es your hot water needs,

a means such as a *Mixing Valve, should be used at the hot

water taps used by these people or at the water heater. Mix-

ing valves are available at plumbing supply or hardware stores.

Consult a Qualiﬁ ed Installer or Service Agency. Follow mixing

valve manufacturer’s instructions for installation of the valves.

Before changing the factory setting on the thermostat, read the

“Temperature Regulation” section in this manual.

FACTS TO CONSIDER ABOUT THE LOCATION

Carefully choose an indoor location for the new water heater,

because the placement is a very important consideration for the

safety of the occupants in the building and for the most eco-

nomical use of the appliance. This water heater is not for use in

manufactured (mobile) homes or outdoor installation.

Whether replacing an old water heater or putting the water heater

in a new location, the following critical points must be observed:

1. Select a location indoors as close as practical to the vent

terminal or location to which the water heater vent piping is

going to be connected, and as centralized with the water pip-

ing system as possible.

2. Selected location must provide adequate clearances for ser-

vicing and proper operation of the water heater.

Installation of the water heater must be accomplished in such a

manner that if the tank or any connections should leak, the ﬂ ow

will not cause damage to the structure. For this reason, it is not

advisable to install the water heater in an attic or upper ﬂ oor.

When such locations cannot be avoided, a suitable drain pan

should be installed under the water heater. Drain pans are avail-

able at your local hardware store. Such a drain pan must have

a minimum length and width of at least 2 in. (51mm) greater that

the water heater dimensions and must be piped to an adequate

drain. The pan must not restrict combustion air ﬂ ow.

Water heater life depends upon water quality, water pressure

and the environment in which the water heater is installed. Water

heaters are sometimes installed in locations where leakage may

result in property damage, even with the use of a drain pan piped

to a drain. However, unanticipated damage can be reduced or

prevented by a leak detector or water shut-off device used in

conjunction with a piped drain pan. These devices are available

from some plumbing supply wholesalers and retailers, and de-

tect and react to leakage in various ways:

• Sensors mounted in the drain pan that trigger an alarm or

turn off the incoming water to the water heater when leakage

is detected.

• Sensors mounted in the drain pan that turn off the water sup-

ply to the entire home when water is detected in the drain

pan.

• Water supply shut-off devices that activate based on the wa-

ter pressure differential between the cold water and hot water

pipes connected to the water heater.

• Devices that will turn off the gas supply to a gas water heater

while at the same time shutting off its water supply.

Also, the water heater must be located and/or protected so it is

not subject to physical damage by a moving vehicle.

This water heater must not be installed directly on carpeting.

Carpeting must be protected by metal or wood panel beneath

the appliance extending beyond the full width and depth of the

appliance by at least 3 in. (76mm) in any direction, or if the ap-

pliance is installed in an alcove or closet, the entire ﬂ oor must be

covered by the panel. Failure to heed this warning may result

in a ﬁ re hazard.

LOCATING THE NEW WATER HEATER

INSULATION BLANKETS

Insulation blankets available to the general public for external use

on gas water heaters are not necessary with this product. The

purpose of an insulation blanket is to reduce the standby heat

loss encountered with storage tank water heaters. Your Water

heater meets or exceeds the National Appliance Energy Conser-

vation Act standards with respect to insulation and standby loss

requirements, making an insulation blanket unnecessary.

Should you choose to apply an insulation blanket to this heater,

you should follow these instructions (See Figure 1 for identiﬁ ca-

tion of components mentioned below). Failure to follow these

instructions can restrict the air ﬂ ow required for proper combus-

tion, resulting in ﬁ re, asphyxiation, serious personal injury or

death.

• Do not cover the outer door, thermostat or temperature &

pressure relief valve.

• Do not cover the instruction manual. Keep it on the side of

the water heater or nearby for future reference.

• Do obtain new warning and instruction labels from the manu-

facturer for placement on the blanket directly over the exist-

ing labels.

VENTILATION FOR APPLIANCES LOCATED IN

CONFINED SPACES

FIGURE 3

Conﬁ ned Space is a space whose volume is less than 50 cubic

feet per 1,000 Btu per hour (4.8 cm per kW) of the aggregate

input rating of all appliances installed in that space.

VENT TERMINATION

Before installing water heater determine placement of vent ter-

mination.

Make certain to observe vent location limitation, see Figures 3,

4 & 11.

Minimum clearances between the water heater

and combustible and noncombustible construction are: 0 in.

(0mm) from sides, 0 in. (0mm) from back, 4 in. (102mm) from

front of jacket to closet door and 20 in. (508mm) from top of

jacket to combustible and noncombustible material. Minimum

vent clearance: 1 in. (25mm)*. Provide 3 ft. (915mm) front clear-

ance for servicing and adequate clearance between the jacket

top & ceiling for servicing the ﬂ ue area, see Figure 4.

* Where the wall is combustible and the wall thickness is over

14 in. (356mm), 1 in. (25mm) clearance to combustible materials

around the vent terminal is needed. The ﬁ rst 14 in. (356mm) is

zero clearance.

Make certain the vent locations comply with the National Fuel

Gas Code ANSI Z223.1/NFPA 54 and/or local codes. There is

some important information shown in Figure 11.

For a second or more direct vent unit, the distance between vent

terminals must be a minimum of 12 in. (305mm).

FIGURE 4

REQUIRED ABILITY

INSTALLATION OR SERVICE OF THIS WATER HEATER

REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED

TRADESMAN IN THE FIELD INVOLVED. PLUMBING, AIR

SUPPLY, VENTING AND GAS SUPPLY ARE REQUIRED.

INSPECT SHIPMENT

There may be hidden damage caused in transit. Check to

be certain all parts of the venting system, as listed below,

are present. CAUTION!!! IF THERE ARE ANY DAMAGED

PARTS, DO NOT INSTALL THIS WATER HEATER. REPORT

ANY SHORTAGE TO YOUR DISTRIBUTOR OR DAMAGE TO

YOUR CARRIER.

GENERAL

The installation must conform to these instructions and the lo-

cal code authority having jurisdiction. In the absence of local

codes, the installation must comply with the current editions of

the National Fuel Gas Code ANSI Z223.1/NFPA 54. The code is

available from the Canadian Standards Association, 8501 East

Pleasant Valley Road, Cleveland, OH 44131.

WATER PIPING

HOTTER WATER CAN SCALD:

Water heaters are intended to produce hot water. Water heated

to a temperature which will satisfy space heating, clothes wash-

ing, dish washing, cleaning and other sanitizing needs can scald

and permanently injure you upon contact. Some people are

more likely to be permanently injured by hot water than others.

These include the elderly, children, the inﬁ rm, or physically/men-

tally handicapped. If anyone using hot water in your home ﬁ ts

into one of these groups or if there is a local code or state law

requiring a certain temperature water at the hot water tap, then

you must take special precautions. In addition to using the low-

est possible temperature setting that satisﬁ es your hot water

needs, a means such as a *mixing valve, should be used at the

hot water taps used by these people or at the water heater, see

Figure 2. Valves for reducing point of use temperature by mixing

cold and hot water are also available:

Consult a Qualiﬁ ed Installer or Service Agency. Follow man-

ufacturer’s instructions for installation of the valves. Before

changing the factory setting on the thermostat, read the “Tem-

perature Regulation” section in this manual.

This water heater shall not be connected to any heating systems

or component(s) used with a non-potable water heating appli-

ance.

All piping components connected to this unit for space heating

applications shall be suitable for use with potable water.

Toxic chemicals, such as those used for boiler treatment shall

not be introduced into this system.

When the system requires water for space heating at tem-

peratures higher than required for domestic water purposes, a

tempering valve must be installed. Please refer to Figure 2 for

suggested piping arrangement.

Water supply systems may, because of such events as high line

pressure, frequent cut-offs, the effects of water hammer among

others, have installed devices such as pressure reducing valves,

check valves, back ﬂ ow preventers, etc. to control these types of

problems. When these devices are not equipped with an internal

by-pass, and no other measures are taken, the devices cause

the water system to be closed. As water is heated, it expands

(thermal expansion) and closed systems do not allow for the

expansion of heated water.

The water within the water heater tank expands as it is heated

and increases the pressure of the water system. If the relieving

point of the water heater’s temperature-pressure relief valve

is reached, the valve will relieve the excess pressure. The

temperature-pressure relief valve is not intended for the

constant relief of thermal expansion. This is an unacceptable

condition and must be corrected.

It is recommended that any devices installed which could create

a closed system have a by-pass and/or the system have an ex-

pansion tank to relieve the pressure built by thermal expansion

in the water system. Expansion tanks are available for ordering

through a local plumbing contractor. Contact the local water

supplier and/or a service agency for assistance in controlling

these situations.

NOTE: To protect against untimely corrosion of hot and cold

water ﬁ ttings, it is strongly recommended that di-electric

unions or couplings be installed on this water heater when

connected to copper pipe.

All gas piping must comply with local codes and ordinances or

with the National Fuel Gas Code ANSI Z223.1/NFPA 54 which-

ever applies. Copper and brass tubing and ﬁ ttings (except tin

lined copper tubing) shall not be used.

Figure 5 shows the typical attachment of the water piping to the

water heater. The water heater is equipped with 3/4“ NPT water

connections.

NOTE: If using copper tubing, solder tubing to an adapter before

attaching the adapter to the cold water inlet connection. Do not

solder the cold water supply line directly to the cold water inlet.

It will harm the dip tube and damage the tank.

T & P VALVE AND PIPE INSULATION (IF SUPPLIED)

Remove insulation for T & P valve and pipe connections from

carton.

FIGURE 6

Fit pipe insulation over the incoming cold water line and the hot

water line. Make sure that the insulation is against the top cover

of the heater.

Fit T & P valve insulation over valve. Make sure that the insula-

tion does not interfere with the lever of the T & P valve.

Secure all insulation using tape.

TEMPERATURE-PRESSURE RELIEF VALVE

This heater is provided with a properly certiﬁ ed combination

temperature - pressure relief valve by the manufacturer.

The valve is certiﬁ ed by a nationally recognized testing labora-

tory that maintains periodic inspection of production of listed

equipment of materials as meeting the requirements for Relief

Valves for Hot Water Supply Systems, ANSI Z21.22 • CSA 4.4,

and the code requirements of ASME.

If replaced, the valve must meet the requirements of local codes,

but not less than a combination temperature and pressure relief

valve certiﬁ ed as indicated in the above paragraph.

The valve must be marked with a maximum set pressure not to ex-

ceed the marked hydrostatic working pressure of the water heater

(150 psi = 1,035 kPa) and a discharge capacity not less than the

water heater input rate as shown on the model rating plate.

For safe operation of the water heater, the relief valve must not

be removed from its designated opening nor plugged.

The temperature-pressure relief valve must be installed directly

into the ﬁ tting of the water heater designed for the relief valve.

Position the valve downward and provide tubing so that any

discharge will exit only within 6 in. (152mm) above, or at any

distance below the structural ﬂ oor. Be certain that no contact is

made with any live electrical part. The discharge opening must

not be blocked or reduced in size under any circumstances.

Excessive length, over 30 ft. (9.14m), or use of more than four

elbows can cause restriction and reduce the discharge capacity

of the valve, see Figures 5 or 10.

No valve or other obstruction is to be placed between the relief

valve and the tank. Do not connect tubing directly to discharge

drain unless a 6 in. (152mm) air gap is provided. To prevent

bodily injury, hazard to life, or property damage, the relief valve

must be allowed to discharge water in quantities should circum-

stances demand. If the discharge pipe is not connected to a

drain or other suitable means, the water ﬂ ow may cause property

damage.

The Discharge Pipe:

• Shall not be smaller in size than the outlet pipe size of the

valve, or have any reducing couplings or other restrictions.

• Shall not be plugged or blocked.

• Shall be of material listed for hot water distribution.

• Shall be installed so as to allow complete drainage of both

the temperature-pressure relief valve, and the discharge

pipe.

• Shall terminate at an adequate drain.

• Shall not have any valve between the relief valve and tank.

The temperature-pressure relief valve must be manually oper-

ated at least once a year. Caution should be taken to ensure that

(1) no one is in front of or around the outlet of the temperature-

pressure relief valve discharge line, and (2) the water manually

discharged will not cause any bodily injury or property damage

because the water may be extremely hot.

If after manually operating the valve, it fails to completely reset

and continues to release water, immediately close the cold water

inlet to the water heater, follow the draining instructions, and re-

place the temperature-pressure relief valve with a new one.

WATER (POTABLE) HEATING AND SPACE HEATING

1. All piping components connected to this unit for space heating

applications shall be suitable for use with potable water.

2. Toxic chemicals, such as those used for boiler treatment,

shall NEVER be introduced into this system.

3. This unit may NEVER be connected to any existing heating

system or component(s) previously used with a non-potable

water heating appliance.

4. When the system requires water for space heating at

temperatures higher than required for domestic water

purposes, a tempering valve must be installed, see Figure 7

for suggested piping arrangement.

FIGURE 7

CLOSED WATER SYSTEM

A closed system will exist if a back-ﬂ ow preventer (check valve),

pressure reducing valve, or other similar device is installed in

the cold water line between the water heater and the street main

(or well). Excessive pressure may develop due to the thermal

expansion of heated water causing premature tank failure or

intermittent relief valve operation. This type of failure is not

covered by the limited warranty. An expansion tank may be

necessary in the cold water supply to alleviate this situation, see

Figure 1. Contact the local plumbing authority.

If the temperature and pressure relief valve on the appliance

discharges periodically, this may be due to thermal expansion

in a closed water supply system. Contact the water supplier or

local plumbing inspector on how to correct this situation. DO

NOT PLUG THE TEMPERATURE AND PRESSURE RELIEF

VALVE.

GAS PIPING

Make sure the gas supplied is the same type listed on the model

rating plate. The inlet gas pressure must not exceed 14 inch

water column (3.5 kPa) for natural and propane gas (L.P.). The

minimum inlet gas pressure shown on the rating plate is that

which will permit ﬁ ring at rated input.

All gas piping must comply with local codes and ordinances or

with the National Fuel Gas Code ANSI Z223.1/NFPA 54 which-

ever applies. Copper and brass tubing and ﬁ ttings (except tin

lined copper tubing) shall not be used.

If the gas control valve is subjected to pressures exceeding 1/2

psi (3.5 kPa), the damage to the gas control valve could result in

a ﬁ re or explosion from leaking gas.

If the main gas line Shut-off serving all gas appliances is used,

also turn “off” the gas at each appliance. Leave all gas appli-

ances shut “off” until the water heater installation is complete.

A gas line of sufﬁ cient size must be run to the water heater.

Consult the current edition of National Fuel Gas Code ANSI

Z223.1/NFPA 54 and your gas supplier concerning pipe

size.

There must be:

• A readily accessible manual shut off valve in the gas supply

line serving the water heater, and

• A drip leg (sediment trap) ahead of the gas control valve to

help prevent dirt and foreign materials from entering the gas

control valve.

• A ﬂ exible gas connector or a ground joint union between the

shut off valve and control valve to permit servicing of the

unit.

Be sure to check all the gas piping for leaks before lighting the

water heater. Use a soapy water solution, not a match or open

ﬂ ame. Rinse off soapy solution and wipe dry.

When installed at elevations above 7,700 feet (2,347 meters), input

rating should be reduced at the rate of 4 percent for each 1,000 feet

(305 meters) above sea level which requires replacement of the

burner oriﬁ ce in accordance with National Fuel Gas Code ANSI

Z223.1/NFPA 54. Contact your local gas supplier for further

information.

Failure to replace the standard oriﬁ ce with a high altitude oriﬁ ce

when installed could result in improper and inefﬁ cient operation

of the appliance, producing carbon monoxide gas in excess of

safe limits, which could result in serious injury or death. Contact

your gas supplier for any speciﬁ c changes which may be re-

quired in your area.

Use pipe joint compound or teﬂ on tape marked as being resis-

tant to the action of petroleum [Propane (L.P.)] gases.

The appliance and its gas connection must be leak tested before

placing the appliance in operation.

The appliance and its individual Shut-off valve shall be disconnected

from the gas supply piping system during any pressure testing of

that system at test pressures in excess of 1/2 pound per square inch

(3.5 kPa). It shall be isolated from the gas supply piping system

by closing its individual manual Shut-off valve during any pres-

sure testing of the gas supply piping system at test pressures

equal to or less than 1/2 pound per square inch (3.5 kPa).

Connecting the gas piping to the gas control valve of the water

heater can be accomplished by either of the two methods shown

in Figures 8 and 9.

FIGURE 8 GAS PIPING WITH

FLEXIBLE CONNECTOR.

FIGURE 9 GAS PIPING WITH ALL

BLACK IRON PIPE TO GAS CONTROL.

SEDIMENT TRAPS

A sediment trap shall be installed as close to the inlet of the

water heater as practical at the time of water heater installation.

The sediment trap shall be either a tee ﬁ tting with a capped

nipple in the bottom outlet or other device recognized as an ef-

fective sediment trap. If a tee ﬁ tting is used, it shall be installed

in conformance with one of the methods of installation shown in

Figures 8 and 9.

Contaminants in the gas lines may cause improper operation of

the gas control valve that may result in ﬁ re or explosion. Before

attaching the gas line be sure that all gas pipe is clean on the in-

side. To trap any dirt or foreign material in the gas supply line, a

drip leg (sometimes called a sediment trap) must be incorporat-

ed in the piping. The drip leg must be readily accessible. Install

in accordance with the “Gas Piping” section. Refer to the current

edition of the National Fuel Gas Code ANSI Z223.1/NFPA 54.

FILLING THE WATER HEATER

Never use this water heater unless it is completely full of water.

To prevent damage to the tank, the tank must be ﬁ lled with water.

Water must ﬂ ow from the hot water faucet before turning “ON”

gas to the water heater.

To ﬁ ll the water heater with water:

1. Close the water heater drain valve by turning the handle to

the right (clockwise). The drain valve is on the lower front of

the water heater.

2. Open the cold water supply valve to the water heater.

NOTE: The cold water supply valve must be left open when

the water heater is in use.

3. To insure complete ﬁ lling of the tank, allow air to exit by open-

ing the nearest hot water faucet. Allow water to run until a

constant ﬂ ow is obtained. This will let air out of the water

heater and the piping.

4. Check all water piping and connections for leaks. Repair as

needed.

VENTING

NEVER OPERATE THE HEATER UNLESS IT IS VENTED TO

THE OUTDOORS AND HAS ADEQUATE AIR SUPPLY TO

AVOID RISKS OF IMPROPER OPERATION, FIRE, EXPLOSION

OR ASPHYXIATION.

DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND

VENTILATING AIR. ADEQUATE AIR FOR COMBUSTION

AND VENTILATION MUST BE PROVIDED FOR SAFE

OPERATION.

HIGH ALTITUDE INSTALLATIONS

Installations above 7,700 ft. (2347 m) require replacement of the

burner oriﬁ ce in accordance with the National Fuel Gas Code

ANSI Z223.1/NFPA 54. Failure to replace the oriﬁ ce could result

in improper and inefﬁ cient operation of the appliance, producing

carbon monoxide gas in excess of safe limits, which could result

in serious personal injury or death. Contact your gas supplier for

any speciﬁ c changes which may be required in your area.

COMBUSTION AIR AND VENTILATION

When determining the installation location for a direct vent water

heater, snow accumulation and drifting should be considered in

areas where applicable.

VENT TERMINAL CLEARANCES

The vent system must terminate so that proper clearances are

maintained as cited in local codes or the current edition of the

WHAT TO DO IF YOU SMELL GAS

• Do not try to light any appliance.

• Do not touch any electric switch; do not use any phone

in your building.

• Immediately call your gas supplier from a neighbor's

phone. Follow the gas supplier's instructions.

• If you cannot reach your gas supplier, call the fire

department.

C. Use only your hand to push in or turn the gas control

knob. Never use tools. If the knob will not push in or turn

by hand, don't try to repair it, call a qualified service

technician. Force or attempted repair may result in a fire

or explosion.

D. Do not use this appliance if any part has been

underwater. Immediately contact a qualified installer or

service agency to replace a flooded water heater.Do not

attempt to repair the unit! It must be replaced!

BEFORE LIGHTING: ENTIRE SYSTEM MUST BE FILLED WITH WATER AND AIR PURGED FROM ALL LINES

FOR YOUR SAFETY READ BEFORE LIGHTING

TEMPERATURE REGULATION

HOT WATER CAN SCALD: Water heaters are intended to

produce hot water. Water heated to a temperature that will

satisfy space heating, clothes washing, dish washing, and other

sanitizing needs can scald and permanently injure you upon

contact. Some people are more likely to be permanently injured

by hot water than others. These include the elderly, children, the

inﬁ rm, or physically/mentally handicapped. If anyone using hot

water in your home ﬁ ts into one of these groups or if there is a

provincial, state law or local code requiring a speciﬁ c hot water

temperature at the tap, then you must take special precautions.

Never allow small children to use a hot water tap, or to draw

their own bath water. Never leave a child or handicapped person

unattended in a bathtub or shower.

It is recommended that lower water temperatures be used to

avoid the risk of scalding. It is further recommended, in all cases,

that the water temperature be set for the lowest temperature that

satisﬁ es your hot water needs. This will also provide the most

energy efﬁ cient operation of the water heater.

Figure 29 shows the approximate water temperatures produced

at various thermostat dial settings. Short repeated heating

cycles caused by small hot water uses can cause temperatures

at the point of use to exceed the thermostat setting by up to 30°F

(17°C). If you experience this type of use you should consider

using lower temperature settings to reduce scald hazards.

Valves for reducing point-of-use temperature by mixing cold

and hot water are available (see Figures 2 & 7). Also available

are inexpensive devices that attach to faucets to limit hot water

temperatures. Contact a licensed plumber or the local plumbing

authority.

SHOULD OVERHEATING OCCUR OR THE GAS SUPPLY FAIL

TO SHUT OFF, TURN OFF THE MAIN MANUAL GAS CON-

TROL VALVE TO THE APPLIANCE (SEE FIGURE 1).

NOTE: A water temperature range of 120°F-140°F (49°C-60°C)

is recommended by most dishwasher manufacturers. The ther-

mostat of this water heater has been factory set at its lowest

position (PILOT LIGHTING). It is adjustable and must be reset

to the desired temperature setting to reduce the risk of scald

injury. The mark ( ) indicative of approximately 120°F (49°C)

is preferred starting point. Some provinces may have a require-

ment for a lower setting.

Turn the water temperature dial clockwise ( ) to decrease the

temperature, or counterclockwise ( ) to increase the tempera-

ture.
